Senior Machine Learning Engineer

What We Need

You are an exceptional software engineer with a strong track record of deploying and operating ML models in production, particularly as low-latency, high-availability prediction services. You can deploy ML models as real-time, near-real-time, or batch services depending on the requirements of the use case. You bring deep, hands-on machine learning experience with a working command of ML algorithm types and tasks, the end-to-end ML lifecycle, and modern modeling and serving frameworks.

You operate with autonomy and judgment. You're a solution-oriented, creative problem solver and a self-starter who drives initiatives end-to-end: scoping ambiguous problems, making sound architectural choices across multi-component systems, and shipping to deadline. As a senior engineer, you raise the bar around you by setting technical direction, mentoring others, and championing engineering standards across the team and wider ML community.

What You Will Do

• Partner with ML scientists, data engineers, central tech, and game studios to deploy ML models as production-grade decision services and integrate them into larger systems and live products.
• Own and mature Machine Learning Ops practice: CI/CD for models, model registry and feature stores, real-time inference at scale, monitoring, drift detection, and reproducibility. Advocate for engineering best practices across the community.
• Design and rapidly prototype ML-powered products for applications including recommenders, matchmaking, cheat/toxicity intervention, and economy balancing.
• Work closely with studio devs and central tech to plan and execute the integration of ML applications into games on launch timelines.
• Identify, evaluate, and pilot opportunities to apply GenAI/LLM to enable new use cases, and translate promising concepts into secure, scalable, and measurable solutions.

What Will Make You A Great Fit

• Bachelor's degree in Computer Science, Computer/Electrical Engineering, or a related STEM field and 4+ years in software development/engineering, including substantial experience deploying ML in production, or Master's degree with 2-4 years of relevant experience.
• Strong programming skills, proficient in Python. Familiarity with a high-performance systems language (C, C++, Java, Rust, …) is a plus. Comfortable across object-oriented and functional paradigms, and quick to pick up new languages as needed.
• Solid grounding in common ML tasks (supervised and unsupervised; reinforcement learning a plus) and commonly used algorithms across traditional ML and deep learning, with the ability to learn new approaches quickly.
• Hands-on with modern ML frameworks such asPyTorch, TensorFlow, scikit-learn, or Spark ML.
• Production experience with cloud infrastructure (AWS, GCP, or Azure), containers and orchestration (e.g. Kubernetes), serverless, and microservice architecture.
• Hands-on with MLOps and CI/CD tooling including model registries, feature stores, pipeline orchestration (e.g. Airflow, Kubeflow, or MLflow), and automated training, deployment, and monitoring.
• Experience with modern data technologies such as relational and NoSQL databases, and lakehouse/big-data tooling such as Apache Spark or Databricks/Delta.
• Flexibility to start and end late to offer a couple of hours overlap with our US HQ (core hours approximately 10:00–18:30 local) to enable close collaboration.

Nice To Have

• Experience with recommender systems, search algorithms, matchmaking, or reinforcement learning technologies.
• Experience with infrastructure-as-code and infrastructure automation tools, such as Terraform, or AWS CloudFormation.
• Experience with managed ML platforms such as Amazon SageMaker or Databricks.
• Familiarity with stream processing tools such as Apache Kafka, Kinesis, or Spark Streaming.
• Familiarity with GenAI and LLM application patterns and technologies, including RAG, evaluation and guardrails, agentic workflows, or vector databases.
• Major game engines such as Unreal or Unity.
